Patent CA-2167601-A1 (CA)
Inventor: HART RICHARD E
IPC: C08G18/48
Filed: 1994-03-10
Abstract: A water based, solvent free, two component polyurethane-polyurea dispersion containing up to 65% solids.  The first component is a polyester-polyol phase and an aqueous amine phase mixture.  The polyester-polyol is a combination of modified polyester-polyols, low viscosity polyether or polyester-polyols, chain extending low molecular weight polyols, neutralizing amines and a detergent.  It has a solids content of 90-100% and is totally hydroxyl functional with  a carboxylic acid number of 10 and 50, a hydroxyl number of 180 and 300, an equivalent weight range of 165 and 365 and a viscosity of 600-1500 cps at 25 °C.  The amine phase is a combination of neutralizing and chain extending amines having ratios preformulated  to provide a balanced chain extending cross-linking reaction in aqueous phase with -NCO reactive groups.  The aqueous amine blend has an equivalent weight of 40 to 50 and a solids content of 40-60%.  The polyester-polyol and amine phases are combined in water at room temperature to form an aqueous component having a solids content of 33 to 48% and has an equivalent ratio between polyester-polyol phase and amine phase of 1.75:1 to 2.25:2.  The second component is a 100% solids aliphatic isocyanate having a viscosity of between 1000-3500 cps at 25°C and provides an NCO to functional groups in the polyester-polyol/amine component ratio of between about 1:1.3 to 1:1.7.  This solvent free dispersion dries to a film coating having properties equal to conventional solvent based polyurethane coatings.

Title: Vertical-axis hydroelectric machine
Inventor: SCHWANDA JOSEF
IPC: H02K9/00
Filed: 1996-02-14
Abstract: The vertical-axis hydroelectric machine has a rotor star, which is provided with a hub (3) and on the outer periphery of which a rotor rim (7) is arranged. The  latter carries rotor poles  (14),  laminated from pole plates, and pole windings (15). The stator plate body  (18)  is  likewise  laminated from plates  and is provided  with  slots  at  the  inner  periphery  for accommodating a stator winding (28), which has stator winding ends (41, 42) and winding connections at both end faces of the plate body. Both rotor rim (7)  and stator  plate  body  (18)  are  provided  with  radially running cooling slits (9, 19) through which cooling air can be passed from the hub through said slits (9)  in the rotor rim, the distances  (16)  between the poles, the air gap (17) and the slits (19) in the stator plate body (18) into an annular space surrounding the latter and equipped with coolers (23) and from there back to the hub (3). In the process, the rotor acts as delivery and pressure-generating means for the cooling air.        To partition off the machine air gap (17) from the winding-end space (39, 40), sealing plates (24) are fastened to the rotor poles  (14)  at both end faces, which sealing plates (24) extend into the machine air gap (17) up close to the stator bore and are arranged close together as viewed in the peripheral direction, if need be while leaving small gaps (34). In this way, they form an annular seal. The winding end (41, 42) and the winding connections thus lie in the fresh air flow behind the coolers (23)  and are cooled in an optimum manner.
Patent CA-2170827-A1 (CA)
Inventor: OSTERRIED JOSEF
IPC: H05B41/38
Filed: 1996-03-01
Abstract: To increase the operating efficiency of an operating circuit for a high-pressure discharge lamp (LP), current is supplied to the discharge lamp in discontinuous mode, that is, in pulses which start from a zero or null current level when the lamp is operating in normal state. Current flow through a choke coil (LD), which alternately stores and releases energy, is sensed, and a new energy pulse is supplied only when the current through the choke coil has decayed to zero or null, by controlling a pulse width modulation circuit (P2) which, in turn, controls a transistor (T2) which, in turn controls current flow through the coil (LD). The transistor (T2) is a field effect transistor which has its source terminal connected to the negative terminal of an intermediate coupling capacitor (C1) forming part of the power supply for the lamp. A free wheeling diode (D1) is provided, connected to the positive terminal of the intermediate circuit capacitor (C1). After energization, and ignition of the lamp, the lamp is operated in continuous mode, with continuous current flow, to shorten the run-on or warm-up period thereof, switch-over to the discontinued mode operation being gradual as voltage and current supplied to the lamp reach normal operating state.
Patent CA-2174242-A1 (CA)
Title: Method and system for processing first and second digital signal versions of a signal in a diversity receiver
Inventor: ZASTERA BRUCE JOSEPH
IPC: H04B7/08
Filed: 1995-07-20
Abstract: A system for digital selection diversity includes receiving different versions of a signal at different antennas (222, 226) of a receiver (210), and processing the different versions on separate branches each having a digital downconverter (224, 228) and filter (232, 236). The filters are controlled by a diversity switch selector (250) so that one acts to filter (the active branch), and the others decimate their respective input signal versions, based on detected signal quality. The diversity switch selector also controls a demodulator (240) to demodulate the filtered signal. The decimated signals are used to provide both signal quality information, and phase history when a branch becomes active. When the signal quality on an inactive branch is determined to be the greatest, the diversity switch controller controls that branch's filter to switch to a filter mode, and the demodulator to use the last decimated sample for phase history when initially demodulating the signal version coming from the newly active branch.

Title: Sensor system for controlling ventilation systems in vehicles
Inventor: RUMP HANNS
IPC: B60H3/00
Filed: 1995-04-06
Abstract: A sensor system to control the ventilation systems in vehicles in recirculation or air input mode, dependent on the concentration of pollutants in the air outside the vehicle, contains a gas sensor element (52), the electric resistance of which falls when reducing gases appear, and rises when oxidizing gases appear, and an evaluation unit (51), the output of which is connected to the controller of the ventilation unit. In order to simplify the sensor technology of such a system and in order to make evaluation less complicated, the sensor system is so organized that the increase of a gas sensor signal fed into the evaluation unit (51) for a rise in the concentration of reducing gases is the approximate quantitative equivalent of the fall of the signal fed into the evaluation unit (51) for a corresponding rise in the concentration of oxidizing gases, so that the evaluation unit (51) can measure per unit of time the rise or fall in the gas sensor signal fed in, and that the evaluation unit (51) generates a switch signal to adjust the ventilation system to recirculation mode, as soon as the measured rise or fall in the gas sensor signal per unit of time quantitatively exceeds a certain threshold limit.
